Direct Graphene Growth on Metal Oxides by Molecular Epitaxy

Abstract

Direct growth of graphene on Co 3 O 4 (111) at 1000 K was achieved by molecular beam epitaxy from a graphite source. Auger spectroscopy shows a characteristic sp 2 carbon lineshape, at average carbon coverages from 0.4-3 monolayers. Low energy electron diffraction (LEED) indicates (111) ordering of the …
